REST style URLs with HTTP Client

[stampy88]

I am trying to use the HTTP transport Client to consume an existing web service. The problem is that the URLs are REST style, i.e. they are parameterized based on what you are retrieving. An example would be /api/bar/{id} where the variable id would be filled in at request time.

The problem is that the httptransport.NewClient function requires the URL be known at creation time. So my question is what is the go-kit way of handling URLs like this? Create a new Client every time? Modify the URL on the http.Request that is passed into the encode function?

Thanks!

Yes you'd do the latter. An example of a client doing this can be seen here:

It even works if client uses Go kit service discovery. Example down here shows this with setting the baseURL from the emitted new instance:
